Size of nozzle(s) – may need a bigger/smaller one depending on different uses

Battery/Battery longevity – This is needed so it can be used without a cord and used for a good amount of time as well

Weight – Want the Dustbuster to be light enough so that a user’s arm does not get tired holding on to the Dustbuster for even short periods of time

Capacity of dirt chamber – want the chamber to have large capacity so that the holding chamber does not have to be replaced too frequently
